Measuring 1-1/4" x 2-3/4", Topps Peel-Offs were an insert with 1963 Topps baseball cards. There are 46 players in the unnumbered set, each pictured in a color photo inside an oval with the player's name, team and position in a band below. The back of the Peel-Off is removable, leaving a sticky surface that made the Peel-Off a popular decorative item among youngsters of the day. Naturally, that makes them quite scarce today. The stickers can be found both blank-backed and with instructions printed on the peel-off backing. - 2006 Standard Catalog of Baseball Cards, 15th Edition.
